The phrase 'had better' is a modal expression used to give strong advice or a warning.
It must be followed by the base form of the verb, also known as the bare infinitive (the verb without 'to').
The correct structure is: Subject + had better + [base verb].
In this sentence, 'consult' is the base verb that correctly follows 'had better'.
Why Other Options Were Wrong
Option A: 'Consulted' is the past tense/past participle form of the verb. Modal expressions like 'had better' are not followed by past tense verbs.
Option C: 'To consult' is the full infinitive form. The rule for 'had better' specifically requires the bare infinitive, meaning the 'to' must be omitted.
Option D: 'Consultation' is a noun, meaning a meeting with an expert for advice. The grammatical structure after 'had better' requires a verb (an action word), not a noun.
